Here’s my early 80’s Guerciotti (59 cm). I bought this as a junior in high school when I was into the idea of bike racing. Top riders in the Tour de France rode bikes like this. It’s still a wonderful bike and I use it for most many of my Friday excursions. It’s been modified from it’s original condition in the following ways: I’ve put wider, more comfortable tires on clincher rims (sew-ups originally), re-tapped the handlebars with hemp-twine and three coats of shellac, added a Brooks saddle, and attached a front rack. She’s relatively light, fast, and can hold extra clothes, food, a camera, or whatever in the old TA bag.
